I know that this question has been raised numerous time, even i have seen in SCN also.
But the problem is currently client is using one oracle based ERP, and in this ERP client can do the batch posting of payment run post check generation.
As i i know this is not possible in standard SAP. Can anyone let me know is there any way out so that we can get the customize transaction code develop with the help of ABAPER .
Second problem is same time they want to do the payment with different bank from single payment run. I know this possible with the help " Reallocate" option while editing payment run. Since system will pay the item from the bank maintained in ranking order but the problem is system will print the check as per the check variant given in driver program "RFFOUS_C". While testing system is printing check only against those payment document No where in
house bank and account id is matching with 1st ranking order and variant maintained in "RFFOUS_C"
